Jonathan Ternynck is one of the pre-made townies in The Sims 2 who resides in Veronaville. He can be made playable by marrying him or befriending and asking him to move in. Jonathan has short gelled brown hair and a grey pinstriped outfit with a dusty pink tie.

Like all townies in The Sims 2, Jonathan's career, skills and relationships with other townies are usually randomized at the start of the game. He has the same facial structure as Nathen Custer.
